Abstract

En mobilbrukermottaker konfigurert til å fjerne valgte signaler fra et trafikksignal før dekoding innbefatter en mottaker med en mottakerinngang konfigurert til å motta kommunikasjonssignaler fra en sender over et radiogrensesnitt. Mottakerinngangen blir levert til en trafikksignalkansellerer som kansellerer uønskede trafikksignaler, og til en pilotsignalkansellerer som fjerner et globalpilotsignal. Utgangen fra pilotsignalkansellereren subtraheres fra utgangen fra trafikksignalkansellereren og skaffer en mottakerutgang uten uønskede trafikksignaler og globalpilotsignaler.
